SPECIFICATION forming part of Letters Patent No. 642,397, dated January 30, 1900.

Application filed June 21, 1899. Serial No. 721.398. (No model.)

To all whom it may concern:

Be it known that we, EDMUND O. WESTER- VELT and CHARLES W. CLAPP, of South Bend St. Joseph county, Indiana, have invented certain new and useful Improvements in Cultivators; and we hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompan yin g drawings, which form part of this specification.

This invention is an improvement in cultivators especially designed for cultivating rows of small plants or young corn; and its object is to provide a machine which can be adapted to various widths of furrows, can easily be controlled by the plowman, and in which the depth of the furrow or cuts can be regulated, and, further, if desired, the shovels can be raised clear of the ground during transportation of the apparatus.

Further objects of the invention are to provide novel adjusting devices for the shafts and novel connections between the cultivator-beams and the frame and draft-beam; and the invention consists in the novel constructions and combinations of parts hereinafter claimed and described in detail with reference to the accompanying drawings, forming part of this specification.

Referring to said drawings, Figure l is a perspective view of the complete cultivator. Fig. 2 is a side elevation thereof. Fig. 3 is a longitudinal section thereof. Fig. 4 is an enlarged perspective view of the several parts of the connection between the cultivatorbeam, the frame, and the draft-bars disconnected. Fig. 5 is a detail perspective view of the cultivator-bar-spreading wedge. Fig. 6 is a detail transverse section, enlarged, on line 9 9, Fig. 2. Fig. 7 is an enlarged perspect-ive view of the shovel attaching and adjusting devices. Fig. 8 is an enlarged horizontal section on line 7 7, Fig. 6. Fig. 9 is a detail perspective view of the reverse parts of the shovel-attaching device disconnected. Fig. 10 is a detail perspective view of handleadjusting casting and wedge-plate. Fig. 11 is a plan view of the shoes.

A designates the frame of the machine, preferably T shaped and constructed of metal, and to the opposite ends of the head of this frame are pivotally connected the opposite cultivator-beams B. Each cultivatorbeam is preferably composed of two bars B B, parallel at their forward portions, but diverging at their rear portions, and to the diverging ends of these bars are connected the shovels C O.

The connection between the cultivator beams and the head of the frame is one of the novel features of this invention and is shown in detail in Fig. 4, and referring thereto'D designates a casting, one of which is secured to each end of the head of frame A. The casting is provided with slots D for the passage of retaining-bolts which are secured to said head, and is also provided at its projecting extremity with horizontal eyes 61, arranged one vertically over the other and sufficiently separated to allowa loop eon the end of draftbeam D to be inserted between the eyes (1. To the front ends of the bars B composing the cultivator-beam are bolted the castings F f, which castings are adapted to respectively fit over the bottom and one side and top and other side of the end of the beam and are secured thereto by means of transverse bolts 13*, which pass through perforations and f in the vertical Webs of castings F f, as shown. The horizontal portions of these castings may be provided with ribs F and f to separate the members B of the beams, if desired. The horizontal portions of these castings are respectively provided with projecting ears F and f from the inner faces of which extend tapered lugs F and f which lugs are adapted to pass through the eyes 61 of casting D, thereby securing the cultivator beam to the frame, and to meet in the loop 6, thereby securing the draft-beam E to the head and to the cultivator-beam. The simplicity and utility of this construction will be posed extension, in which is a large eye Z2, and in rear of this is a curved slot W. In this eye b is fitted the cylindrical boss g of a casting g, having a slot 9 registering with a slot b and having in its face, opposite the boss g, a vertical semicylindrical groove 9 Beside the castings b g is a casting G, which is provided at one end with a curved slot G (through which passes the bolt B and at its other end with a curved slot G adapted to register with the slots 9 and 19 all of said slots being transfixed by the same bolt G Casting G is also provided with a vertically-disposed semicylindrical recess G which is opposite the recess g in casting g, and through these coincident grooves G 9 passes the shovel-supporting rod 0, supporting on its lower end the shovel C. By reference to the drawings it will be observed that while casting I) is rigid with the bar B the castings G g are adjustable in relation thereto, so that the shovel-supporting rods can be adjusted to differentaugles relatively to the bars 13. Thus the shovels can be adjusted to any position desired by the operator.

At the point where the bars B diverge the handle supporting casting H is attached. This casting is provided with an upwardly and rearwardly inclined extension II, to which handle H may be attached in the usual manner. Underneath the plate H and interposed between the bars B is a wedge-plate casting h, which is provided with a wedge portion h, which projects between the bars B and is adapted to separate the latter more or less, according as the wed ge-plate is adjusted more or less toward the front end of the bars. The castings H h are secured in position and together by means of through-bolts 7L2, casting II being provided with a slot H to permit the adjustment of wedge-plate 7t.

To the stem of the frame A, just in rear of its head, is pivoted a bent lever I, which is provided with a rearwardly-extending handle portion I, adapted to engage the ratcheted keeper 1*, attached to the rear extremity of the stem of the frame, as shown. The lever I below the pivot is bent forwardly and downwardly and extends beyond the front of the frame, as shown at 1 and this portion 1 is provided with bearings for the wheel I, as shown. The parts I I I of the lever may be made in one piece or in sections rigidly united, so that when the handle I is depressed the wheel I will be elevated, and vice versa. Upon the stem of the frame, in rear of the pivot of lever I, are pivoted the opposite runners or shoes i, which diverge as shown. The upper ends of the shoes normally project above the stem of the frame and are connected by a link 11' to the lever I below the pivot thereof, as shown, so that the lower ends of the shoes will be raised or lowered simultaneously with the raising or lowering of the wheel I and be controlled by the same lever I.

By means of the handle I the position of the wheel and shoes can be so adjusted as to cause the shovels to make deep or light furrows, as the operator may desire.

From the foregoing description it will be obvious that we have produced an improved cultivator which has all the necessary adjustments for accoml'nodating it to varying stiffness of the soil, and it can be readily adapted to different kinds and conditions of crops to be cultivated and set to make the shovels operate at any desired depth.

Having thus described our invention, what we therefore claim as new, and desire to secure by Letters Patent thereon, is
